FIELD OF THE INVENTION

This invention relates to novel quinuclidines derivatives,pharmaceutical compositions, and use thereof in treating muscarinicacetylcholine receptor mediated diseases of the respiratory tract.

BACKGROUND OF THE INVENTION

Acetylcholine released from cholinergic neurons in the peripheral andcentral nervous systems affects many different biological processesthrough interaction with two major classes of acetylcholine receptorsthe nicotinic and the muscarinic acetylcholine receptors. Muscarinicacetylcholine receptors (mAChRs) belong to the superfamily of G-proteincoupled receptors that have seven transmembrane domains. There are fivesubtypes of mAChRs, termed M₁-M₅, and each is the product of a distinctgene. Each of these five subtypes displays unique pharmacologicalproperties. Muscarinic acetylcholine receptors are widely distributed invertebrate organs where they mediate many of the vital functions.Muscarinic receptors can mediate both inhibitory and excitatory actions.For example, in smooth muscle found in the airways, M₃ mAChRs mediatecontractile responses. For review, please see Caulfield (1993 Pharmac.Ther. 58:319-79).

In the lungs, mAChRs have been localized to smooth muscle in the tracheaand bronchi, the submucosal glands, and the parasympathetic ganglia.Muscarinic receptor density is greatest in parasympathetic ganglia andthen decreases in density from the submucosal glands to tracheal andthen bronchial smooth muscle. Muscarinic receptors are nearly absentfrom the alveoli. For review of mAChR expression and function in thelungs, please see Fryer and Jacoby (1998 Am J Respir Crit Care Med158(5, pt 3) S 154-60).

Three subtypes of mAChRs have been identified as important in the lungs,M₁, M₂ and M₃ mAChRs. The M₃ mAChRs, located on airway smooth muscle,mediate muscle contraction. Stimulation of M₃ mAChRs activates theenzyme phospholipase C via binding of the stimulatory G protein Gq/11(Gs), leading to liberation of phosphatidyl inositol-4,5-bisphosphate,resulting in phosphorylation of contractile proteins. M₃ mAChRs are alsofound on pulmonary submucosal glands. Stimulation of this population ofM₃ mAChRs results in mucus secretion.

M₂ mAChRs make up approximately 50-80% of the cholinergic receptorpopulation on airway smooth muscles. Although the precise function isstill unknown, they inhibit catecholaminergic relaxation of airwaysmooth muscle via inhibition of cAMP generation. Neuronal M₂ mAChRs arelocated on postganglionic parasympathetic nerves. Under normalphysiologic conditions, neuronal M₂ mAChRs provide tight control ofacetylcholine release from parasympathetic nerves Inhibitory M₂ mAChRshave also been demonstrated on sympathetic nerves in the lungs of somespecies. These receptors inhibit release of noradrenaline, thusdecreasing sympathetic input to the lungs.

M₁ mAChRs are found in the pulmonary parasympathetic ganglia where theyfunction to enhance neurotransmission. These receptors have also beenlocalized to the peripheral lung parenchyma, however their function inthe parenchyma is unknown.

Muscarinic acetylcholine receptor dysfunction in the lungs has beennoted in a variety of different pathophysiological states. Inparticular, in asthma and chronic obstructive pulmonary disease (COPD),inflammatory conditions lead to loss of inhibitory M₂ muscarinicacetylcholine autoreceptor function on parasympathetic nerves supplyingthe pulmonary smooth muscle, causing increased acetylcholine releasefollowing vagal nerve stimulation (Fryer et al. 1999 Life Sci 64 (6-7)449-55). This mAChR dysfunction results in airway hyperreactivity andhyperresponsiveness mediated by increased stimulation of M₃ mAChRs.Thus, the identification of potent mAChR antagonists would be useful astherapeutics in these mAChR-mediated disease states.

COPD is an imprecise term that encompasses a variety of progressivehealth problems including chronic bronchitis, chronic bronchiolitis andemphysema, and it is a major cause of mortality and morbidity in theworld. Smoking is the major risk factor for the development of COPD;nearly 50 million people in the U.S. alone smoke cigarettes, and anestimated 3,000 people take up the habit daily. As a result, COPD isexpected to rank among the top five as a world-wide health burden by theyear 2020. Inhaled anti-cholinergic therapy is currently considered the“gold standard” as first line therapy for COPD (Pauwels et al. 2001 Am.J. Respir. Grit. Care Med. 163:1256-1276).

Despite the large body of evidence supporting the use ofanti-cholinergic therapy for the treatment of airway hyperreactivediseases, relatively few anti-cholinergic compounds are available foruse in the clinic for pulmonary indications. More specifically, inUnited States, Ipratropium Bromide (Atrovent©; and Combivent©, incombination with albuterol) is currently the only inhaledanti-cholinergic marketed for the treatment of airway hyperreactivediseases. While this compound is a potent anti-muscarinic agent, it isshort acting, and thus must be administered as many as four times dailyin order to provide relief for the COPD patient. In Europe and Asia, thelong-acting anti-cholinergic Tiotropium Bromide (Spiriva©) was recentlyapproved; however, this product is currently not available in the UnitedStates. Thus, there remains a need for novel compounds that are capableof causing blockade at mAChRs which are long acting and can beadministered once-daily for the treatment of airway hyperreactivediseases such as asthma and COPD.

Since mAChRs are widely distributed throughout the body, the ability toapply anti-cholinergics locally and/or topically to the respiratorytract is particularly advantageous, as it would allow for lower doses ofthe drug to be utilized. Furthermore, the ability to design topicallyactive drugs that have long duration of action, and in particular, areretained either at the receptor or by the lung, would allow theavoidance of unwanted side effects that may be seen with systemicanti-cholinergic use.

Methods of Preparation

The compounds of Formula (I) may be obtained by applying syntheticprocedures, some of which are illustrated in the Schemes below. Thesynthesis provided in this Scheme is applicable for producing compoundsof Formula (I) having a variety of different R1, R2 and R3 groups whichare reacted, employing substituents which are suitably protected, toachieve compatibility with the reactions outlined herein. Subsequentdeprotection, in those cases, then affords compounds of the naturegenerally disclosed. While the Schemes are shown with compounds only ofFormula (I), this is merely for illustration purpose only.

As shown in Scheme 1, the desired compounds of Formula (I) can beprepared in four synthetic steps from the commercially available ethyl4-piperidinecarboxylate precursor 1. Compound 1 is reacted with1-bromo-2-chloroethane following standard alkylation procedures wellknown in the art such as potassium carbonate in acetone followed byreaction of the intermediate with lithium diisopropylamide in an aproticsolvent such as tetrahydrofurann to give the quinuclidine intermediate2. Condensation of compound 2 with organometallic reagents such as aGrignard reagent or an organolithium derivative in an aprotic solventsuch as tetrahydrofuran, results in the formation of the tertiaryalcohol 3 of Formula (I) (R1=nothing). Further N-alkylation of compound3 with a suitable alkyl halide in a organic solvent such as chloroformor acetontirile gives compound 4 of Formula (I) (R1 not nothing).

Example 1 Preparation of 1-azabicyclo[2.2.2]oct-4-yl(diphenyl)methanolEthyl 1-(2-chloroethyl)-4-piperidinecarboxylate

To a solution of ethyl nipecotate (20.0 mL, 130 mmol) in acetone (180mL) was added 1-bromo-2-chloroethane (21.6 mL, 260 mmol) followed byanhydrous K₂CO₃ (27.12 g, 196 mmol). The reaction mixture was stirredfor 24 h and then concentrated under vacuum. The resulting residue wastreated with H₂O (75 mL) and extracted with Et₂O. The combined organiclayers were dried with MgSO₄, filtered, and concentrated under vacuum.Purification of the crude residue by flash chromatography (50% Et₂O/50%hexane) on silica gel gave the title compound (10.99 g, 38.6%). EI-MSm/z 220 (M+H⁺) Rt (1.20 min).

Ethyl 1-azabicyclo[2.2.2]octane-4-carboxylate

BIOLOGICAL EXAMPLES

The inhibitory effects of compounds at the M₃ mAChR of the presentinvention are determined by the following in vitro and in vivofunctional assays:

Analysis of Inhibition of Receptor Activation by Calcium Mobilization:

Stimulation of mAChRs expressed on CHO cells were analyzed by monitoringreceptor-activated calcium mobilization as previously described (H. M.Sarau et al, 1999. Mol. Pharmacol. 56, 657-663). CHO cells stablyexpressing M₃ mAChRs were plated in 96 well black wall/clear bottomplates. After 18 to 24 hours, media was aspirated and replaced with 100μl of load media (EMEM with Earl's salts, 0.1% RIA-grade BSA (Sigma, St.Louis Mo.), and 4 μM Fluo-3-acetoxymethyl ester fluorescent indicatordye (Fluo-3 AM, Molecular Probes, Eugene, Oreg.) and incubated 1 hr at37° C. The dye-containing media was then aspirated, replaced with freshmedia (without Fluo-3 AM), and cells were incubated for 10 minutes at37° C. Cells were then washed 3 times and incubated for 10 minutes at37° C. in 100 μl of assay buffer (0.1% gelatin (Sigma), 120 mM NaCl, 4.6mM KCl, 1 mM KH₂PO₄, 25 mM NaH CO₃, 1.0 mM CaCl₂, 1.1 mM MgCl₂, 11 mMglucose, 20 mM HEPES (pH 7.4)). 50 μl of compound (1×10⁻¹¹-1×10⁻⁵ Mfinal in the assay) was added and the plates were incubated for 10 min.at 37° C. Plates were then placed into a fluorescent light intensityplate reader (FLIPR, Molecular Probes) where the dye loaded cells wereexposed to excitation light (488 nm) from a 6 watt argon laser. Cellswere activated by adding 50 μl of acetylcholine (0.1-10 nM final),prepared in buffer containing 0.1% BSA, at a rate of 50 μl/sec. Calciummobilization, monitored as change in cytosolic calcium concentration,was measured as change in 566 nm emission intensity. The change inemission intensity is directly related to cytosolic calcium levels. Theemitted fluorescence from all 96 wells is measured simultaneously usinga cooled CCD camera. Data points are collected every second. This datawas then plotting and analyzed using GraphPad PRISM software.

Methacholine-Induced Bronchoconstriction Potency and Duration of Action

Airway responsiveness to methacholine was determined in awake,unrestrained Balb C mice (n=6 each group). Barometric plethysmographywas used to measure enhanced pause (Penh), a unitless measure that hasbeen shown to correlate with the changes in airway resistance that occurduring bronchial challenge with methacholine (2). Mice were pre-treatedwith 50 μl of compound (0.003-10 μg/mouse) in 50 μl of vehicle (10%DMSO) intranasally (i.n.) and were then placed in the plethysmographychamber a given amount of time following drug administration (15 min-96h). For potency determination, a dose response to a given drug wasperformed, and all measurements were taken 15 min following i.n. drugadministration. For duration of action determination, measurements weretaken anywhere from 15 min to 96 hours following i.n. drugadministration.

Once in the chamber, the mice were allowed to equilibrate for 10 minbefore taking a baseline Penh measurement for 5 minutes. Mice were thenchallenged with an aerosol of methacholine (10 mg/ml) for 2 minutes.Penh was recorded continuously for 7 min starting at the inception ofthe methacholine aerosol, and continuing for 5 minutes afterward. Datafor each mouse were analyzed and plotted by using GraphPad PRISMsoftware. This experiment allows the determination of duration ofactivity of the administered compound.

The present compounds are useful for treating a variety of indications,including but not limited to respiratory-tract disorders such as chronicobstructive lung disease, chronic bronchitis, asthma, chronicrespiratory obstruction, pulmonary fibrosis, pulmonary emphysema, andallergic rhinitis.

Muscarinic Receptor Radioligand Binding Assays

Radioligand binding studies using 0.5 nM [³H]-N-methyl scopolamine (NMS)in a SPA format is used to assess binding of muscarinic antagonists toM₁, M₂, M₃, M₄ and M₅ muscarinic acetylcholine receptors. In a 96-wellplate, the SPA beads are pre-incubated with receptor-containing membranefor 30 min at 4° C. Then 50 mM HEPES and the test compound are added andincubated at room temperature (shaking) for 2 hours. The beads are thenspun down and counted using a scintillation counter.

Evaluation of Potency and Duration of Action in Isolated Guinea PigTrachea

Tracheae were removed from adult male Hartely guinea pigs (CharlesRiver, Raleigh, N.C.; 400-600 grams) and placed into modifiedKrebs-Henseleit solution. Composition of the solution was (mM): NaCl113.0, KCl 4.8, CaCl₂ 2.5, KH₂PO₄ 1.2, MgSO₄ 1.2, NaHCO₃ 25.0 anddextrose 11.0, which was gassed with 95% O₂: 5% CO₂ and maintained at37° C. Each trachea was cleaned of adherent tissue and openedlengthwise. Epithelium was removed by gently rubbing the luminal surfacewith a cotton-tipped applicator. Individual strips were cut,approximately 2 cartilage rings in width, and suspended via silk suturein 10-ml water-jacketed organ baths containing Krebs-Henseleit solutionand connected to Grass FT03C force-displacement transducers. Mechanicalresponses were recorded isometrically by MP100WS/Acknowledge dataacquisition system (BIOPAC Systems, Goleta, Calif., www.biopac.com) runon Apple G4 computers. The tissues were equilibrated under a restingtension of 1.5 g, determined to be optimal by length-tension evaluation,and washed with Krebs-Henseleit solution every 15 minutes for one hour.After the equilibration period pulmonary tissues were contracted with 10uM carbachol until reaching plateau, which served as a referencecontraction for data analysis. Tissues were then rinsed every 15 minutesover 1 hour until reaching baseline tone. The preparations were thenleft for at least 30 minutes before the start of the experiment.

Concentration-response curves were obtained by a cumulative addition ofcarbachol in half-log increments (Van Rossum, 1963, Arch. Int.Pharmacodyn., 143:299), initiated at 1 nM. Each concentration was leftin contact with the preparation until the response plateaued before theaddition of the subsequent carbachol concentration. Paired tissues wereexposed to mAChR antagonist compounds or vehicle for 30 min beforecarbachol cumulative concentration-response curves were generated. Alldata is given as mean±standard error of the mean (s.e.m.) with n beingthe number of different animals.

For superfusion (duration of action) studies, the tissues werecontinuously superfused with Krebs-Henseleit solution at 2 ml/min forthe duration of the experiment. Stock solutions of agonist andantagonist were infused (0.02 ml/min). via 22-guage needle inserted intothe superfusion tubing. Mechanical responses were recorded isometricallyusing a commercially-available data acquisition system(MP100WS/Acknowledge; BIOPAC Systems, Goleta, Calif., www.biopac.com)interfaced with a Macintosh G4 computer (Apple, Cupertino, Calif.www.apple.com). The tissues were suspended under an optimal restingtension of 1.5 g. After a 60 min equilibration period, the tissues werecontracted with carbachol (1 uM) for the duration of the experiment.Upon reaching a sustained contraction isoproterenol (10 uM) wasadministered to maximally relax the tissue, and this change served as areference. Isoproterenol exposure was halted and the carbachol-inducedtension allowed to recover. Muscarinic receptor antagonists infused at asingle concentration per tissue until a sustained level of inhibitionwas attained. The compound was then removed and, once again, thecarbachol-induced tension was allowed to recover.

The following parameters were determined for each concentration ofantagonist, and expressed as the mean±S.E.M. for n individual animals.Inhibition of the carbachol-induced contraction was expressed as apercent of the reference response (isoproterenol) and the time requiredto reach one-half of this relaxation was measured (onset of response).The tension recovery following removal of the compound was determined aswas the time required to reach one-half of the maximum tension recovery(offset of response). At 60 and 180 minutes after removal of theantagonist the remaining level of inhibition was determined andexpressed as a percent of the isoproterenol reference.

Antagonist concentration-response curves were obtained by plotting themaximal relaxation data at 0, 60 and 180-min following antagonistwithdrawal. Recovery, termed shift, was calculated from the ratio of the0-min inhibition curve IC₅₀ and the concentration of compound yielding asimilar tension recovery at 60 and 180 minutes.

Halftimes for onset and offset of response were plotted vs.corresponding concentration and the data were fit with non-linearregression. These values were extrapolated at the IC₅₀ (determined fromthe inhibition concentration-response curve) and designated Ot₅₀ (timerequired, at the IC₅₀ concentration, to reach half of the onsetresponse) and Rt50 (time required, at the IC₅₀ concentration, to reachhalf of the recovery response).

Hereinafter, the term “active ingredient” means a compound of formula(I), or a pharmaceutically acceptable salt, solvate, or physiologicallyfunctional derivative thereof.

Compounds of formula (I) will be administered via inhalation via themouth or nose.

Dry powder compositions for topical delivery to the lung by inhalationmay, for example, be presented in capsules and cartridges of for examplegelatine, or blisters of for example laminated aluminium foil, for usein an inhaler or insufflator. Powder blend formulations generallycontain a powder mix for inhalation of the compound of the invention anda suitable powder base (carrier/diluent/excipient substance) such asmono-, di- or poly-saccharides (e.g., lactose or starch), organic orinorganic salts (e.g., calcium chloride, calcium phosphate or sodiumchloride), polyalcohols (e.g., mannitol), or mixtures thereof,alternatively with one or more additional materials, such additivesincluded in the blend formulation to improve chemical and/or physicalstability or performance of the formulation, as discussed below, ormixtures thereof. Use of lactose is preferred. Each capsule or cartridgemay generally contain between 20 μg-10 mg of the compound of formula (I)optionally in combination with another therapeutically activeingredient. Alternatively, the compound of the invention may bepresented without excipients, or may be formed into particles comprisingthe compound, optionally other therapeutically active materials, andexcipient materials, such as by co-precipitation or coating.

Suitably, the medicament dispenser is of a type selected from the groupconsisting of a reservoir dry powder inhaler (RDPI), a multi-dose drypowder inhaler (MDPI), and a metered dose inhaler (MDI).

By reservoir dry powder inhaler (RDPI) it is meant as an inhaler havinga reservoir form pack suitable for comprising multiple (un-metereddoses) of medicament in dry powder form and including means for meteringmedicament dose from the reservoir to a delivery position. The meteringmeans may for example comprise a metering cup or perforated plate, whichis movable from a first position where the cup may be filled withmedicament from the reservoir to a second position where the meteredmedicament dose is made available to the patient for inhalation.

By multi-dose dry powder inhaler (MDPI) is meant an inhaler suitable fordispensing medicament in dry powder form, wherein the medicament iscomprised within a multi-dose pack containing (or otherwise carrying)multiple, define doses (or parts thereof) of medicament. In a preferredaspect, the carrier has a blister pack form, but it could also, forexample, comprise a capsule-based pack form or a carrier onto whichmedicament has been applied by any suitable process including printing,painting and vacuum occlusion.

The formulation can be pre-metered (eg as in Diskus, see GB 2242134 orDiskhaler, see GB 2178965, 2129691 and 2169265) or metered in use (eg asin Turbuhaler, see EP 69715). An example of a unit-dose device isRotahaler (see GB 2064336). The Diskus inhalation device comprises anelongate strip formed from a base sheet having a plurality of recessesspaced along its length and a lid sheet hermetically but peelably sealedthereto to define a plurality of containers, each container havingtherein an inhalable formulation containing a compound of formula (I)preferably combined with lactose. Preferably, the strip is sufficientlyflexible to be wound into a roll. The lid sheet and base sheet willpreferably have leading end portions which are not sealed to one anotherand at least one of the said leading end portions is constructed to beattached to a winding means. Also, preferably the hermetic seal betweenthe base and lid sheets extends over their whole width. The lid sheetmay preferably be peeled from the base sheet in a longitudinal directionfrom a first end of the said base sheet.

In one aspect, the multi-dose pack is a blister pack comprising multipleblisters for containment of medicament in dry powder form. The blistersare typically arranged in regular fashion for ease of release ofmedicament therefrom.

In one aspect, the multi-dose blister pack comprises plural blistersarranged in generally circular fashion on a disk-form blister pack. Inanother aspect, the multi-dose blister pack is elongate in form, forexample comprising a strip or a tape.

Preferably, the multi-dose blister pack is defined between two memberspeelably secured to one another. U.S. Pat. Nos. 5,860,419; 5,873,360;and 5,590,645 describe medicament packs of this general type. In thisaspect, the device is usually provided with an opening stationcomprising peeling means for peeling the members apart to access eachmedicament dose. Suitably, the device is adapted for use where thepeelable members are elongate sheets which define a plurality ofmedicament containers spaced along the length thereof, the device beingprovided with indexing means for indexing each container in turn. Morepreferably, the device is adapted for use where one of the sheets is abase sheet having a plurality of pockets therein, and the other of thesheets is a lid sheet, each pocket and the adjacent part of the lidsheet defining a respective one of the containers, the device comprisingdriving means for pulling the lid sheet and base sheet apart at theopening station.

By metered dose inhaler (MDI) it is meant a medicament dispensersuitable for dispensing medicament in aerosol form, wherein themedicament is comprised in an aerosol container suitable for containinga propellant-based aerosol medicament formulation. The aerosol containeris typically provided with a metering valve, for example a slide valve,for release of the aerosol form medicament formulation to the patient.The aerosol container is generally designed to deliver a predetermineddose of medicament upon each actuation by means of the valve, which canbe opened either by depressing the valve while the container is heldstationary or by depressing the container while the valve is heldstationary.

Spray compositions for topical delivery to the lung by inhalation mayfor example be formulated as aqueous solutions or suspensions or asaerosols delivered from pressurised packs, such as a metered doseinhaler, with the use of a suitable liquefied propellant. Aerosolcompositions suitable for inhalation can be either a suspension or asolution and generally contain the compound of formula (I) optionally incombination with another therapeutically active ingredient and asuitable propellant such as a fluorocarbon or hydrogen-containingchlorofluorocarbon or mixtures thereof, particularly hydrofluoroalkanes,e.g. dichlorodifluoromethane, trichlorofluoromethane,dichlorotetra-fluoroethane, especially 1,1,1,2-tetrafluoroethane,1,1,1,2,3,3,3-heptafluoro-n-propane or a mixture thereof. Carbon dioxideor other suitable gas may also be used as propellant. The aerosolcomposition may be excipient free or may optionally contain additionalformulation excipients well known in the art such as surfactants egoleic acid or lecithin and cosolvents eg ethanol. Pressurisedformulations will generally be retained in a canister (eg an aluminiumcanister) closed with a valve (eg a metering valve) and fitted into anactuator provided with a mouthpiece.

Medicaments for administration by inhalation desirably have a controlledparticle size. The optimum aerodynamic particle size for inhalation intothe bronchial system for localized delivery to the lung is usually 1-10μm, preferably 2-5 μm. The optimum aerodynamic particle size forinhalation into the alveolar region for achieving systemic delivery tothe lung is approximately 0.5-3 μm, preferably 1-3 μm. Particles havingan aerodynamic size above 20 μm are generally too large when inhaled toreach the small airways. Average aerodynamic particle size of aformulation may be measured by, for example cascade impaction. Averagegeometric particle size may be measured, for example by laserdiffraction, optical means.

To achieve a desired particle size, the particles of the activeingredient as produced may be size reduced by conventional means e.g. bycontrolled crystallization, micronisation or nanomilling. The desiredfraction may be separated out by air classification. Alternatively,particles of the desired size may be directly produced, for example byspray drying, controlling the spray drying parameters to generateparticles of the desired size range. Preferably, the particles will becrystalline, although amorphous material may also be employed wheredesirable. When an excipient such as lactose is employed, generally, theparticle size of the excipient will be much greater than the inhaledmedicament within the present invention, such that the “coarse” carrieris non-respirable. When the excipient is lactose it will typically bepresent as milled lactose, wherein not more than 85% of lactoseparticles will have a MMD of 60-90 μm and not less than 15% will have aMMD of less than 15 μm. Additive materials in a dry powder blend inaddition to the carrier may be either respirable, i.e., aerodynamicallyless than 10 microns, or non-respirable, i.e., aerodynamically greaterthan 10 microns.

Suitable additive materials which may be employed include amino acids,such as leucine; water soluble or water insoluble, natural or syntheticsurfactants, such as lecithin (e.g., soya lecithin) and solid statefatty acids (e.g., lauric, palmitic, and stearic acids) and derivativesthereof (such as salts and esters); phosphatidylcholines; sugar esters.Additive materials may also include colorants, taste masking agents(e.g., saccharine), anti-static-agents, lubricants (see, for example,PCT Publication No. WO 87/905213, the teachings of which areincorporated by reference herein), chemical stabilizers, buffers,preservatives, absorption enhancers, and other materials known to thoseof ordinary skill.

Sustained release coating materials (e.g., stearic acid or polymers,e.g. polyvinyl pyrolidone, polylactic acid) may also be employed onactive material or active material containing particles (see, forexample, U.S. Pat. No. 3,634,582; GB 1,230,087; GB 1,381,872, theteachings of which are incorporated by reference herein).

Intranasal sprays may be formulated with aqueous or non-aqueous vehicleswith the addition of agents such as thickening agents, buffer salts oracid or alkali to adjust the pH, isotonicity adjusting agents oranti-oxidants.

Solutions for inhalation by nebulation may be formulated with an aqueousvehicle with the addition of agents such as acid or alkali, buffersalts, isotonicity adjusting agents or antimicrobials. They may besterilised by filtration or heating in an autoclave, or presented as anon-sterile product.

Preferred unit dosage formulations are those containing an effectivedose, as herein before recited, or an appropriate fraction thereof, ofthe active ingredient.
